Left 4 Dead 2

Has anyone ever done this? created a clan for l4d2? not in the general sence, such as a large number of people, but a 4(to suit l4d) person team,each with different skills? I am thinking about starting one. mainly looking for 4 distinct skills. (strategy,shooting,etc) (can't think of another 2) what do you guys think? good idea,bad idea?
